still-water bending moment
Quick Summary
In physics, a bending moment refers to the resultant moment about the neutral axis of a rod or beam caused by forces that induce bending.1
In naval architecture, the bending moment of a ship's hull is calculated to ensure structural integrity. This involves determining the still-water bending moment (when the sea surface is level) and adding a wave-bending moment, which is an empirical calculation based on the ship's size and proportions. This calculation helps predict stresses and deflections within the hull to ensure it can withstand the forces encountered at sea.2
